There is ongoing development in connecting vehicles wirelessly to other vehicles, wayside infrastructure, and cloud-based services. While current connectivity often uses Dedicated Short Range Communications (DSRC), this requires a physical installation and is limited to where it is installed. Cellular is almost ubiquitous, but LTE has too high a latency for safe vehicle operations when microseconds matter. 5G is considered to be the coming platform for V2X communications.
Goals and Objectives
Development of smart roads and highways that provide safer, multimodal roads and reduce roadway/highway system congestion, improved emergency response times, and more efficient routings and information to the driver and occupants.
Mobile, cloud, edge, IoT, sensor integration with other smart devices on national roadway or highway traffic systems to communication-capable vehicles on the road
Use Case Summary
Connected vehicles, through the volume and scale of connectivity, are expanding as other technologies develop, such as road-based sensor infrastructure. This use case includes vehicle-to-vehicle (e.g., government-owned fleets), vehicle-to-infrastructure (e.g., roadway sensors), and vehicle-to-government platforms.
